in Apparatus for Heating, Cooling, or Fasteurizing Liquids, of which the following is a specification.

The object of my invention is to provide sim lo and efficient apparatus for the heating,

coo ing or pasteurization of milk or other liquids, an object which I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which Figure 1 is a vertical sectional View of aparatus constructed in accordance with my invention, and Fig. 2 is a side elevation of the same.

In the drawing, 1-1 represent opposite upright frames or standards having bearings for the shafts or spindles of a series of hollow drums 2, 3, 4 and 5 disposed one above another, one of the shafts of each drum being geared to a corresponding shaft of the next drum through the medium of an idle gear, whereby all of the drums are rotated in the same direction. The other shaft of each drum is hollow for the reception of a pipe 7, whereby water or other heating or cooling fluid can be introduced into the interior of the drum, each of these ipes terminating within the drum in a longitudinal tube 9 located adjacent to the periphery of the drum,

preferably at the top of the same,'and' perfo-.

rated on o posite sides in order to provide 35 for the de ive-ry of the heating or cooling fluid into the drum in the form of jets which impinge upon the inner wall of the drum and flow downwardly on each side of the same so as to heat orco'ol the shell of the drum, the

water or other fluid accumulating in the lower portion of the drum and escaping therefrom through the hollow shaft'as soon as it reaches the level of the latter and the Waste being collected in any suitable recep- 5c ripheral surface.

At the top of the standards 1 is a transverse trough 10, having, in the bottom, out.

lets on op osite sides of a separator plate 11,

whereby t 1e flow from the trough is directed to the uppermost drum on opposite sides of the center of the same, a portion of the flow, therefore, following the surface of'the drum on the descending side of the same and the remaining 'iortion ofthe flow following the surface of t e drum on the ascending side of the same. The flow is limited to such an extent that it forms a realtively thin film on each drum, which has a tendency to adhere to the surface of the drum and follow the same from top to bottom instead of dropping from the surface of the drum at the center of the same as it would have a tendency to do if in larger volume.

At the bottom of the drum is a air of scraper blades 12, which have the e ect of removing the film of liquid from the surface of the drum and directing it onto the upper portion of the drum beneath, and in this way the film of liquid follows'the surface of. each.

drum from top to bottom and is finally removed from the lowermost drum and directed into a receiving trough 13 or other suitable receptacle for the purpose.

If the ap aratus is to be used as a heater all of the rums will be supplied interiorly with steam, hot water, or other heating fluid, while, if, on the other hand, the apparatus is to be used as a cooler a cooling liquid will be supplied in like manner, the temperature of the fluid being preferably increased from drum to drum in succession in the case of a heater, .or being lowered in temperature from drum to drum in succession in the case of a cooler.

The apparatus as shown in the drawing has been designed for use as a pasteurizer, in

which case the upper drums 2 and 3 may be supplied with heating fluid and the lower drums 4 and 5 with cooling fluid. The uppermost drum 2 may be supplied with hot water the next drum 3 with steam, the third drum 4 with cold water, and the lowermost drum 5 with brine, the material increase in the peripheral surface presented by the.

varying the s eed of rotation of the drums,

'care being ta (en, of course, to so limit the speed that the centrifugal action will\not tend to cause the 'film of liquid under treat, ment to be thrown oii from the drum.

Although I have shown the apparatus as of duplexcharacter, that is to say, as providing for the feedingof liquid to be treated to both the descending and ascending sides of each drum, said liquid may be fed to one side of the drum'only, if desired, preferably to the the descending side, and although I prefer in eachcase to use a scraper or scrapers in connection with the under portion of each drum, the use of such scraper or scrapers is not essential to the broader embodiment of my invention.

When the liquid to be treated is applied to one side of the drum only, the internal heatcooling of liquids, said apparatus comprising,

in combination, a series of rotating drums I disposed directly one above another, means cooling ofliquids, said apparatus comprising,
